Yintoni injongo ye-cavity resonator? Isihluzi se-Cavity se-2878-2882MHz kwiiNethiwekhi ze-Passive zanamhlanje

I-cavity resonator igcina amandla e-RF kwipateni yamaza amileyo kwaye iwabuyisela kuphela kwi-frequency ecetywayo.Isihluzi seCavity se-2878-2882MHzIveliswe yiKeenlion eseChengdu isebenzisa lo mgaqo nge-quarter-wave coaxial cavity: iindonga zesilivere ezifakwe kwi-silver-plated zichaza i-2880 MHz eigen-mode, ngelixa amandla e-off-band ebonakala ebuyela kumthombo. Ngenxa yokuba i-2878-2882MHz Cavity Filter ayinazo izinto ezisebenzayo, ilahleko yokufakelwa inqunyelwe kwilahleko zomqhubi kunye ne-dielectric—amaxabiso alinganisiweyo ahlala engaphantsi kwe-1.0 dB kwifestile ye-4 MHz.

Uyilo loBugcisa kunye nokuSebenza

I-2878-2882MHz Cavity Filter isebenzisa ii-high-Q cavities ukuze ifumane ilahleko encinci yokufakwa (≤1.0 dB) kunye nokukhetha okugqwesileyo (ukungafunwa kwe->40 dB kwi-±5 MHz offset). Indlu yayo encinci, enomlinganiselo we-74 × 31 × 30 mm, idityaniswe kakuhle kwiinkqubo ezixinzelelweyo njengee-UAV pods okanye ii-compact IoT radios. I-filter isebenza ngokuthembekileyo kumaqondo obushushu ukusuka kwi--55°C ukuya kwi-85°C, kunye ne-VSWR egcinwe ngaphantsi kwe-1.5:1 ukunciphisa ukubonakaliswa kwesignali. Iyunithi nganye ivavanywa nge-100% ngokuzenzekelayo kwe-VNA ukuqinisekisa iinkcukacha ezifana nokuphathwa kwamandla (20W CW) kunye nokunyuka kwebhendi.

Imvulophu yoomatshini

Ubungakanani obupheleleyo yi-74 × 30 × 31mm—incinci kunezinye izixhobo ze-SAW—kodwa i-2878-2882MHz Cavity Filter iphatha i-20 W CW. Imingxunya emibini ye-M2 kwiziko le-15 mm ivumela i-2878-2882MHz Cavity Filter ukuba inamathele ngqo eludongeni lwe-aluminium, isusa imfuneko yebracket eyahlukileyo kwaye igcina iigram ezixabisekileyo kwi-UAV okanye kwizakhiwo eziphathwa ngesandla.

Umqolo Wefektri

Oomatshini bezityalo zeKeenlion abaneminyaka engama-20, iipleyiti, ii-tunes kunye nee-welds rhoqo emva kwe-2878-2882MHz Cavity Filter phantsi kophahla olunye. Ixesha lokuqalisa liziintsuku ezisixhenxe kwiindawo eziqhelekileyo, iiyure ezingamashumi amane anesibhozo kwiiodolo eziphindaphindwayo. Ukulahleka kokufakwa ≤1.0 dB kunye nokwaliwa ≥40 dB kuqinisekisiwe kwi-2878-2882MHz Cavity Filter nganye; iisampulu zasimahla zithunyelwa ngaphakathi kweeyure ezingamashumi amane anesibhozo kwaye ukwahlulwahlulwa kwamaza okwenzelwe wena kuyamkelwa ngaphandle kwe-MOQ.
